2026-07-09 A dataset of bird diversity and seasonal dynamics in the Qinghai Xining Huangshui River National Wetland Park doi:10.57760/sciencedb.41487 en This dataset originates from systematic bird diversity monitoring conducted in the Qinghai Xining Huangshui River National Wetland Park from January 2022 to May 2025, supplemented by integrated data from the China Bird Report Center and historical literature spanning January 2020 to March 2026. Field surveys employed standardized line transect methods, with investigators walking on foot along riparian beaches, wetlands, and artificial forest habitats within the park's three major sections: Haihu Wetland Park (approximately 1.868 km²), Beichuan River Wetland Park (approximately 2.012 km²), and Ninghu Wetland Park (approximately 0.855 km²). The walking speed was maintained at 1–2 km/h, with a survey frequency of once per month, increasing to 1–2 times per month during peak migration periods. Observations were conducted using binoculars (Zeiss, 8×42) and digital cameras (Nikon P1000, D50) for species identification and photographic documentation. The mobile application "LooKoo Outdoor Assistant" was used to record transect tracks, while "GPS Toolbox" was employed to collect information on bird locations, including longitude, latitude, altitude, species, abundance, sex, age, and behavior, with spatial positioning accuracy at approximately 10 m and temporal resolution at the single survey date level. Bird population counts were recorded using direct counting or flock counting methods; when the same species was repeatedly recorded at the same location, the maximum count was retained to control for duplicate counting errors.Data compilation and quality control followed standardized protocols: dual independent observation and recording were implemented in the field, and questionable species identifications were reviewed by team experts; after data entry, cross-checking was performed to ensure accuracy of the original records. Quantitative analyses were conducted using R 4.4.3 software to calculate species richness (S), Shannon-Wiener diversity index (H′), Pielou evenness index (J), and dominance index (P) for field survey data and data from the China Bird Report Center during 2020–2026, with the reshape2 and ggplot2 packages used to visualize seasonal dynamics of dominant species across ecological guilds. It should be noted that, due to observational constraints, this dataset primarily comprises daytime line transect surveys, with insufficient nighttime survey coverage resulting in missing distribution and abundance information for nocturnal birds (such as some Strigiformes species). Additionally, historical literature data were used solely to supplement the species checklist and rare records, and were not incorporated into quantitative analyses of population abundance and diversity indices.The dataset is stored in Microsoft Excel (*.xlsx) format with a total data volume of approximately 391 KB, and can be opened directly using Microsoft Excel, WPS Office, or compatible spreadsheet software. The dataset comprises a single workbook containing multiple worksheets, specifically including: (1) a bird species checklist systematically cataloging 267 bird species across 19 orders and 58 families, with fields for Chinese name, Latin scientific name, Chinese endemic species designation, protection status, residency type, and abundance level (dominant species/common species/rare species); (2) a line transect survey raw data table organized by survey date, park section, species, population abundance, longitude and latitude (unit: °, six decimal places retained), and altitude (unit: m), with row labels representing species-specific observation records from individual survey events and column labels encompassing temporal, spatial, species, and abundance attributes, where population abundance is measured in "individual counts" and the table covers species-specific observation records from systematic surveys; (3) a seasonal dynamics statistics table providing Shannon diversity index and Pielou evenness index for spring, summer, autumn, and winter; and (4) an ecological guild dominant species data table presenting dominance indices (%) for dominant species across six guilds—terrestrial birds, raptors, passerines, climbing birds, waders, and waterfowl—in different seasons, to support the construction of seasonal dynamic bubble charts. The worksheets are interlinked through species names to facilitate cross-table integration and secondary analysis. bird diversity; wetland ecology; seasonal dynamics; long-term monitoring; plateau urban wetland Li Guogang Sun Nan Zhou Na Liu Jun Chen Yanchao Gama Chenglinqiujiang Li Ji He Shunfu Liu Yanlin Zhong Yuetao Mao Xiaoning Zhang Xiaoning Zhang Guoming PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
